Step-by-step explanation:
4x -y =2
-y = -4x + 2
y = 4x -2
slope = 4
perpendicular slope is negative inverse
so -1/4
y- -2 = -1/4(x - 4)
y+2 = -1/4x +1
y = -1/4x -1
First put both in other
24,26,27,30,31,32,32 = 30
29,29,29.5,30,32 =29.5
add them together
=59.5
or if your question is all the numbers together
24,26,27,29.5,29,29,30,30,31,32,32,32= 29+30
= 29.9
2n^2-8n=9
divide by 2
2(n^2-4n) =9
add (4/2)^2 =4 to each side completing the square
(n^2-4n+4 ) =9/2+4
(n-2)^2 = 9/2+8/2
(n-2)^2 =17/2
take the square root of each side
n-2 = +-sqrt(17/2)
add 2 to each side
n = 2+- sqrt (17/2)
Answer:2+ sqrt (17/2),2- sqrt (17/2)
